Leisure-time organised physical activity and dietary intake among Swedish adolescents.

This study aimed to investigate associations between participation in leisure-time organised physical activity (LTOPA) and dietary intake in a large representative sample of Swedish adolescents participating in the national dietary survey Riksmaten Adolescents 2016-2017. A sample of 2807 participants aged 11-12, 14-15 and 17-18 years were included. Information about LTOPA and dietary intake were collected through questionnaires and two 24-hour recalls on the web (RiksmatenFlex).

Organised physical activity during leisure time is associated with more objectively measured physical activity among Swedish adolescents.

Aim: The aim of this study was to investigate associations between participation in organised physical activity (PA), such as sport and exercise during leisure time, and objectively measured PA and sedentary time in a large representative sample of Swedish adolescents.

Methods: This study was part of the school-based cross-sectional Swedish national dietary survey Riksmaten Adolescents 2016-17. Data from 3477 adolescents aged 11-12, 14-15 and 17-18 years were used in the analyses.

Riksmaten Adolescents 2016-17: A national dietary survey in Sweden - design, methods, and participation.

Background: Nationally representative information on food consumption data is essential to evaluate dietary habits, inform policy-making and nutritional guidelines, as well as forming a basis for risk assessment and identification of risk groups.

Objective: To describe the methods used in the Swedish national dietary survey of adolescents, Riksmaten Adolescents 2016-2017.

Design: Students in grades 5, 8, and 11 (mean ages 12, 15, and 18 years) were recruited in this school-based cross-sectional survey.

Sociodemographic and lifestyle factors as determinants of energy intake and macronutrient composition: a 10-year follow-up after bariatric surgery.

Background: Early identification of the potential to adopt a long-term unhealthy diet, could improve weight outcomes for patients having undergone bariatric surgery.

Objectives: We explored whether presurgical sociodemographic and lifestyle characteristics, together with the type of surgery, could predict 10-year changes in dietary intake after bariatric surgery.

Setting: Surgical departments and primary healthcare centers, nationwide.

Changes in total energy intake and macronutrient composition after bariatric surgery predict long-term weight outcome: findings from the Swedish Obese Subjects (SOS) study.

Approximately 20-30% of obese patients do not achieve successful weight outcomes after bariatric surgery. We examined whether short-term changes (≤0.5 y postsurgery) in energy intake and macronutrient composition after bariatric surgery could predict 10-y weight change.

Dietary patterns, cardiometabolic risk factors, and the incidence of cardiovascular disease in severe obesity.

Objective: The longitudinal associations between a dietary pattern (DP) and cardiometabolic risk factors and cardiovascular disease (CVD) incidence were investigated in a cohort of adults with severe obesity.

Methods: The analysis included 2,037 individuals with severe obesity (>34 and >38 kg/m(2) for men and women, respectively) from the Swedish Obese Subjects study repeatedly followed up for 10 years. Reduced rank regression was used to identify a DP characterized by dietary energy density, saturated fat intake, and fiber density.

Long-term effect of bariatric surgery on liver enzymes in the Swedish Obese Subjects (SOS) study.

Background And Aim: Obesity is associated with elevated serum transaminase levels and non-alcoholic fatty liver disease and weight loss is a recommended therapeutic strategy. Bariatric surgery is effective in obtaining and maintaining weight loss. Aim of the present study was to examine the long-term effects of bariatric surgery on transaminase levels in obese individuals.

Alcohol consumption and alcohol problems after bariatric surgery in the Swedish obese subjects study.

Objective: Increased sensitivity to alcohol after gastric bypass has been described. The aim of this study was to investigate whether bariatric surgery is associated with alcohol problems.

Design And Methods: The prospective, controlled Swedish Obese Subjects (SOS) study enrolled 2,010 obese patients who underwent bariatric surgery (68% vertical banded gastroplasty (VBG), 19% banding, and 13% gastric bypass) and 2,037 matched controls.

Bariatric surgery and long-term cardiovascular events.

Context: Obesity is a risk factor for cardiovascular events. Weight loss might protect against cardiovascular events, but solid evidence is lacking.

Objective: To study the association between bariatric surgery, weight loss, and cardiovascular events.

Effects of bariatric surgery on cancer incidence in obese patients in Sweden (Swedish Obese Subjects Study): a prospective, controlled intervention trial.

Background: Obesity is a risk factor for cancer. Intentional weight loss in the obese might protect against malignancy, but evidence is limited. To our knowledge, the Swedish Obese Subjects (SOS) study is the first intervention trial in the obese population to provide prospective, controlled cancer-incidence data.

Prevalence of night eating in obese and nonobese twins.

The aim of this study was to assess the prevalence of night eating (NE) and associated symptoms in a population-based sample of Swedish twins. A total of 21,741 individuals aged 20-47 years completed a questionnaire in 2005/2006. NE was defined as >/=25% of daily food intake after the evening meal and/or awakening at least once per week with eating episodes.

Three definitions of the metabolic syndrome: relations to mortality and atherosclerotic morbidity.

Background: Different definitions of the metabolic syndrome are used, and at least one of these does not include indices of glucose intolerance and/or insulin resistance as obligatory components. In this paper, we examine the predictive power of indices having and not having these obligatory components.

Methods: A total of 1135 men and women, aged 37-61 years, were randomly selected from the populations of Mölndal and Orebro, Sweden.

Effects of bariatric surgery on mortality in Swedish obese subjects.

Background: Obesity is associated with increased mortality. Weight loss improves cardiovascular risk factors, but no prospective interventional studies have reported whether weight loss decreases overall mortality. In fact, many observational studies suggest that weight reduction is associated with increased mortality.

Lifestyle, diabetes, and cardiovascular risk factors 10 years after bariatric surgery.

Background: Weight loss is associated with short-term amelioration and prevention of metabolic and cardiovascular risk, but whether these benefits persist over time is unknown.

Methods: The prospective, controlled Swedish Obese Subjects Study involved obese subjects who underwent gastric surgery and contemporaneously matched, conventionally treated obese control subjects. We now report follow-up data for subjects (mean age, 48 years; mean body-mass index, 41) who had been enrolled for at least 2 years (4047 subjects) or 10 years (1703 subjects) before the analysis (January 1, 2004).
